SO/ Paris
A behemoth 1960s administrative building has become one of Paris's hottest hotels, sought after for its glam interiors, fashion credentials, and show-stealing views that are second only to the Eiffel Tower. Set across from the Île St-Louis, the hotel has stunning vistas that encompass all of Paris, depending on the exact location of your room. Luxe, streamlined guest rooms show a midcentury modern elegance, highlighting natural materials (leather, lustrous wood, wool carpets), plush furnishings, and marble baths. Take in breathtaking 360-degree panoramas from the 16th-floor bar, or have breakfast at the in-hotel restaurant Bonnie with its stunning vistas by day (with outdoor seating in summer). It's so glamorous even Emily in Paris had a romantic fling here.
